Route 256

Sewer pipe to be replaced, but no road closures expected

A $300,000 project to replace a failing storm sewer along state Route 256 will use "cured in-place pipe", a trenchless technology used for rehabilitating underground pipelines.

Layne Inliner LLC of Hilliard submitted the low bid of $246,760 for the project.

City Engineer Greg Bachman said 74 percent of the construction costs will be paid using an Ohio Public Works Commission grant, "leaving $64,157.60 in city costs."

Bachman said the city's share will come from its stormwater utility fund.

He said Layne Inliner LLC will have 90 days to complete the project once Pickerington City Council "accepts their bid and their contract is signed, probably in mid-October."

The affected storm sewer runs beneath the sidewalk on the east side of state Rout 256, from Refugee Road to 2,400 feet north of Refugee Road.

"The pipe has become oval-shaped or squished," Bachman said. "We are having a contractor insert a cured in-place pipe to strengthen the existing pipe."

He said the cured in-place pipe is "basically a soft liner that is inserted into an existing pipe through manholes.

"The liner is inverted and saturated with a resin," he explained. "The inverted pipe is then pressurized with hot water and the liner fills out to the dimension of the existing pipe.

"The resin cures, leaving a liner with structural integrity, which reinforces the existing pipe."

Bachman said that by eliminating the need to dig trenches, CIPP saves time and money, maintains the flow of traffic and helps preserve above-ground foliage and infrastructure.

He added that doing the project without CIPP would result in prolonged traffic issues on the city's most heavily traveled road.

"The alternative to what we're doing is to dig that pipe up to replace it. And for that, we would have to close lanes on Route 256," he said.
